2019 will see the launch of the EQC – the primary all-electric Mercedes-Benz mannequin from the brand new product and expertise model EQ. Between January and March, prototypes of the brand new mannequin collection accomplished powerful winter testing in northern Sweden. The following waystations on the street to collection manufacturing are extra suspension/powertrain exams in addition to built-in complete-vehicle high-temperature testing in southern Europe. Systematic complete-vehicle validation serves to ensure our top quality requirements and is likely one of the in depth measures within the growth course of of each Mercedes-Benz mannequin collection.
Earlier than going into manufacturing, a brand new car should attain a maturity degree particularly outlined by Mercedes-Benz.
Testing: a significant precursor to the launch of each car
Completely digital: Digital testing covers all key areas of car growth: from simulation and validation of building feasibility to crash efficiency, aerodynamics, journey & dealing with, NVH (noise/vibration/harshness), weight via to consumption and vary.
From laptop display screen to check bench and onto the street: Regardless of all some great benefits of digital testing when it comes to pace, knowledge availability and effectivity – no car goes into collection manufacturing with out in depth real-world testing. The main focus right here is on the sturdiness of parts similar to drivetrains on the take a look at bench and the purposeful testing of your complete car below varied weather conditions on the street. Within the case of the EQC, after all, particular consideration is paid to the electrical powertrain and the battery. They too are examined and permitted in accordance with Mercedes-Benz’s extraordinarily strict requirements.
All the things a query of proportion: A particular position can also be performed by the acoustics of an electrical car, as, not like in a combustion-engined car, there’s hardly a sound from the powertrain. This makes sounds such because the rolling of the tyres or wind noise extra distinguished. To satisfy these particular necessities, we depend on our a few years of expertise within the space of NVH (Noise, Vibration, Harshness).
One third/two thirds: With a ratio of 35% to 65% between digital testing and real-world testing, we mix the very best of each worlds – within the pursuits of the customary top quality requirements of Mercedes-Benz.
Nearly 200: That is what number of prototypes and preproduction autos are constructed and examined for this objective in our workshops.
A number of hundred: Earlier than being launched for manufacturing, the car have to be examined and validated by quite a few people from many various growth departments. A complete of a number of hundred specialists are concerned in testing. From the specialist departments, which approve their parts and modules, via to testing/endurance testing of the whole car.
Round 4 years: All in all, the EQC could have been in growth for round 4 years.
Three winters and three summers: The EQC will likely be subjected over three winters and three summers to excessive circumstances from minus 35° to over plus 50° Celsius.
A real cosmopolitan: Earlier than coming to market in lots of international locations around the globe, the EQC could have undergone in depth testing in Germany, Finland, Sweden, Spain, Italy, Dubai, South Africa, the USA and China.
To satisfy the targets for each element and the whole car, the EQC will quickly bear a stress programme within the warmth of Spain. Right here the results of temperature throughout driving is examined below excessive circumstances, and likewise different notably difficult elements for an electrical car, similar to air-con and charging. As a result of one factor is evident: the EQC should provide the standard and driving expertise of each Mercedes-Benz.
